本研究评估了重型公路车辆应用中使用的立方氮化硼（CBN）地面准双曲面齿轮的性能。该测试将齿轮组与各种加工组合进行比较，包括评估研磨效果。耐久性性能通过测功机试验进行验证。使用声压、声功率和单侧测量进行噪声分析。在CBN地面和重叠准双曲面齿轮组的测功机试验中，观察到与传统切割和重叠齿轮组相比，弯曲寿命提高了100%。CBN地面和搭接准双曲面齿轮组的声功率降低超过150%。未封盖CBN齿轮组的耐久性性能优势未得到认可。

THIS INVESTIGATION EVALUATES THE PERFORMANCE OF CUBIC BORON NITRIDE (CBN) GROUND HYPOID GEARS USED IN HEAVY ON-HIGHWAY VEHICLE APPLICATIONS. THE TEST COMPARES GEAR SETS WITH VARIOUS PROCESSING COMBINATIONS INCLUDING AN EVALUATION OF LAPPING EFFECTS. DURABILITY PERFORMANCE WAS VERIFIED USING DYNAMOMETER TESTS. NOISE ANALYSIS WAS PERFORMED USING SOUND PRESSURE, SOUND POWER, AND SINGLE- FLANK MEASUREMENTS. A 100% BENDING LIFE INCREASE OVER CONVENTIONAL CUT AND LAPPED GEAR SETS WAS OBSERVED IN DYNAMOMETER TESTS OF CBN GROUND AND LAPPED HYPOID GEAR SETS. A SOUND POWER REDUCTION OF MORE THAN 150% WAS MEASURED FOR CBN GROUND AND LAPPED HYPOID GEAR SETS. NO DURABILITY PERFORMANCE BENEFITS WERE RECOGNIZED FOR UNLAPPED CBN GEAR SETS.
